This application (available here) can be used for plotting Attenuation Relationship curves.
The first step is to select an Attenuation Relationship from the "Choose Model" pick list (located directly above the plot window). The options include most of those listed here.
Next, choose an IMT from the pick list at the upper right (the options depend on what's supported by your chosen Attenuation Relationship).
Below that, choose from among the following to plot on the Y-axis:
The next step is to choose what you want to plot on the X-axis. The options are generally any independent Parameter of your chosen Attenuation Relationship that represents a numerical value (the options also depend on what you've chosen for the Y-axis).
Finally, set all the other independent Parameters that your chosen Attenuation Relationship depends upon (the list, which is on the lower right, depends on what you've chosen for the Y-axis).
Click here for more info about setting parameters.
HINT: mousing over the parameter name should give you more info about that Parameter, and mousing over where you enter numerical values will show any constraints on the allowed values (either the absolute or warning constraint of the Parameter).
Click the "Add Curve" button to calculate and show the plot.
You can add multiple curves, but the plot will automatically clear if you change what's plotted on either axis (e.g., you can't have both magnitude and distance on the X-axis; however, you can plot different Distance Parameters simultaneously on the X-axis).
The "Clear Plot" button clears the plot.
The "Peel-Off" button sets the current plot aside in a new window (e.g., to save it while you generate new plots).
The "Add Data Points" button allows you to add your own data (e.g., values observed from an actual earthquake).
All other features of this application are part of our standard XY Plot Gui (click for explanation). The functionality of the other buttons at the bottom, however, should be self explanatory.
